Improved Fault Tolerance for Parallel FFT

Abstract

Digital filters are mainly used in signal processing and communication systems. Soft errors are major threats of the modern communication system. Now a day’s complexity of communication and signal processing increases day by day. So reliability of the system is critical and fault tolerance technique is needed. In parallel FFT protection using ECC and parseval check can be used for error detection and correction. In this project is to reduce the entire area of the fault tolerant system by using pipelined method. In pipelined FFT consist of two butterfly structure. Each stage is replaced by a single butterfly structure. Experimental results show that proposed technique reduces the area and delay of the system. This project is mainly focused on the area of the system. Proposed technique is more efficient and reduces the complexity of the entire system.
